Sharing some tips with you to gain some extra fps by fixing the random low gpu usage common issue. I have a fair good gaming pc ( i7 10700K and RTX 3080) and i thought ''can it run crysis'' ?...and it didn't as i expected to. Fiddling with some settings did make the game to run much better. So what i did was this: -> disable full screen optimization option from the exe's properties in Bin64 main installation folder and change to high quality the objects,shadows and vegetation options in advanced configs leaving the rest on "can it run crysis". Now my gpu stays above 90% all the time as you can see in my screenshots below. All this with minimal to no visual loss and enjoyable frames...(100 + in my case). Hope this works for you people as well, just give it a try. Enjoy Crysis.
